Performance data & application area
Refrigeration capacity: 180 kW – Ideal for efficient cooling of large halls or commercial areas.
Heating capacity: 290 kW – Highly efficient air heating through clever use of waste heat from the refrigeration cycle.
Dehumidification capacity: approx. 100 liters per hour – Perfect for precise humidity control.

Application areas: Due to these combined performance data, the unit is ideally suited for industrial production halls, large warehouses, logistics centers, or for demanding process cooling and commercial dehumidification.

The following precise operating temperatures can be derived from the technical specifications and design data in the documentation for the Heck DVAS 180:

1. Refrigeration core area
Evaporation temperature: The unit is designed for an evaporation temperature of 6 °C.
Condensation temperature (liquefaction): The water-cooled plate condenser operates at a condensation temperature of 43 °C.

2. Air-side temperature ranges (process air)
Depending on which ventilation or unit (e.g., cabin, cooling zone, or ADZ unit) is used, the air inlet and outlet temperatures vary:

Standard cooling zone: Air inlet at 26.5 °C is cooled down to an air outlet temperature of 19 °C.
Cabin air conditioning (ULA): Air inlet at 26 °C is conditioned to an air outlet temperature of 22 °C.
Process air dehumidification (ADZ): The air enters at 26 °C and leaves the evaporator strongly dehumidified at 10.3 °C.

Reheating (ADZ unit): A water-cooled reheater can raise the cooled air from 10 °C back to 17.5 °C.

3. Water-side temperature ranges (cooling water / heat recovery)

Plate condenser (condenser cooling): Is designed for a water inlet of 32 °C and a water outlet of 38 °C (at a flow rate of 35 m³/h).
Plate heat exchanger (heat recovery): Uses the hot gas energy to heat water from 42 °C to 47 °C.
